| Abstract: | Under VDSM techno logy, higher device densities and faster switching speed can cause large switchi ng current that degrades the performance and reliability of a design. Robust P/G networks become one of the most importa nt factors to ensure performance, reliab ility and signal integrity of the circui ts. An RLC-based approach for estimating simultaneous switching noi se through supply lines is presented. To simplify, event-driven mechanism, node regrouping and parameter recoding are us ed to set up the path for transmitting switching currents to the destination. S imulation results show the feasibility a nd efficiency of our method. |
